2015 Chevrolet Volt
small car / 4-door sedan
Small overlap front: driver-side
Rating applies to 2014-15 models
Tested vehicle: 2014 Chevrolet Volt 4-door
The Chevrolet Volt was introduced in the 2011 model year. The car is a plug-in battery-electric/gasoline hybrid, featuring an electric-only mode with a range of 38 miles for 2014 models according to the EPA. After the electric-only mode ends, the gas engine kicks in to power the vehicle.
Beginning with 2014 models, the front structure was modified to improve occupant protection in small overlap frontal crashes.

| Driver restraints and dummy kinematics The dummy’s head barely contacted the frontal airbag before sliding off the left side, leaving the head vulnerable to contact with forward structure. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects. |
Action shot taken during the small overlap frontal crash test.
The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained reasonably well.
During the crash, the dummy's head and torso barely contacted the frontal airbag before sliding off to the left. The side curtain airbag extended far enough forward toward the A-pillar to protect the head from contact with forward side structure.
The driver's space was maintained reasonably well, and risk of injuries to the dummy's legs and feet was low.

Action shot taken during the frontal offset crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained very well.
Smeared greasepaint indicates where the dummy's head contacted the side curtain airbag during rebound.
Intrusion into the driver's space was minimal, and all leg and foot injury measures were low.
